Revert "Revert "KGSL: Simple Governor: so I kinda butchered in a good way of course the original code from faux, but the simplicity is still here. Added an history so that we can track the average do that the frequency scaling is much more proporcional to the actual GPU load rather than having is ramp up every now and then due to spurious load spike. Also remove two useless ifs.""

cgroup: Take css_set_lock from cgroup_css_sets_empty()

As indicated in the comment above cgroup_css_sets_empty it needs the
css_set_lock. But neither of the 2 call points have it, so rather then fixing
the callers just take the lock inside cgroup_css_sets_empty().

cgroup: Fix use after free of cgrp (cgrp->css_sets)

Running a 3.4 kernel + Fedora-18 (systemd) userland on my Allwinner A10
(arm cortex a8), I'm seeing repeated, reproducable list_del list corruption
errors when build with CONFIG_DEBUG_LIST, and the backtrace always shows
free_css_set_work as the function making the problematic list_del call.

I've tracked this doen to a use after free of the cgrp struct, specifically
of the cgrp->css_sets list_head, which gets cleared by free_css_set_work.

Since free_css_set_work runs form a workqueue, it is possible for it to not be
done with clearing the list when the cgrp gets free-ed. To avoid this the code
adding the links increases cgrp->count, and the freeing code running from the
workqueue decreases cgrp->count *after* doing list_del, and then if the count
goes to 0 calls cgroup_wakeup_rmdir_waiter().

However cgroup_rmdir() is missing a check for cgrp->count != 0, causing it
to still continue with the rmdir (which leads to the free-ing of the cgrp),
before free_css_set_work is done. Sometimes the free-ed memory is re-used
before free_css_set_work gets around to unlinking link->cgrp_link_list,
triggering the list_del list corruption messages.

This patch fixes this by properly checking for cgrp->count != 0 and waiting
for the cgroup_rmdir_waitq in that case.

usb: core: Limit HCD old enumeration scheme request to root ports

HCD_OLD_ENUM HCD flag is introduced to use old (or short) enumeration
scheme for the devices attached on the corresponding USB bus. The old
enumeration scheme is used by the MSM HSIC controller to avoid multiple
reset during enumeration. This is useful when a known device is attached
to the USB bus, which is the case with MSM HSIC. When a HSIC HUB is
connected, any device can be connected on the HSIC USB bus. The new
enumeration scheme supports wide variety of USB devices. Hence limit
the old enumeration scheme request of a HCD to only root ports.
